What is the answer to the factor equation of 12 1/3 subtract 5 2/3

Fynjy0 [20]

Answer:

The answer to the factor expression is $\frac{20}{3}$

Therefore $12\frac{1}{3}-5\frac{2}{3}=\frac{20}{3}$

Step-by-step explanation:

Given that the factor expression is $12\frac{1}{3}-5\frac{2}{3}$

Now convert the mixed fraction into improper fraction as below :

$12\frac{1}{3}-5\frac{2}{3}=\frac{37}{3}-\frac{17}{3}$

$=\frac{37-17}{3}$

$=\frac{20}{3}$

Therefore $12\frac{1}{3}-5\frac{2}{3}=\frac{20}{3}$

The answer to the factor expression is $\frac{20}{3}$

Vilka [71]

Answer:

Step-by-step explanation:

The computation of the number of people in the chorus are 50 or older is as follows

According to the attached figure

In the age of 50 - 60 , there is 8 people

In the age of 60 - 70 , there is 4 people

In the age of 70 -80, there is 1 people

So, if we do the total that comes

= 8 people + 4 people + 1 people

= 13 people

Hence, the no of people would be 13
